Title: Alkali-resistant refractory and its application
Inventor: OOHASHI KAZUYA
IPC: F27D1/00
Filed: 1997-10-16
Abstract: PROBLEM TO BE SOLVED: To obtain an alkali-resistant refractory excellent in applicability, hardly generating the peeling and drop of the refractory, excellent in adhesivity to water pipes and studs and inhibiting the permeation and erosion of an alkaline smelt by applying a coating material comprising MgO powder and sodium silicate or a coating material comprising the sodium silicate alone to the surface of a sprayed refractory or castable refractory in the oven. SOLUTION: A coating material comprising MgO powder or sodium silicate and used for covering a refractory is applied to the wall surface of an oven made from a known spraying material or castable material comprising one or more kinds of known aggregates selected from aggregates (e.g. sintered alumina) and alumina cement as a curing agent so that the coating material can correspond to an alkaline smelt. The coating material is directly coated on the surface of the sprayed refractory. Thereby, the reaction with the strongly alkaline smelt is concentrated on the surface of the refractory, and the production of the highly viscous alkali-silica reaction product prevents the permeation of the alkali into the refractory.

Title: Treatment of excavated soil
Inventor: NAMIKI SHIGETSUGU
IPC: E02D7/24
Filed: 1985-12-19
Abstract: PURPOSE:To discharge and treat excavated soil without occurrence of pollution of the surrounding area of excavated site by a method in which a treating tank is set around the opening of a casing for excavation and mud water coming from the casing is received by the treating tank and then transported through a drain pipe. CONSTITUTION:A treating tank 1 is set by positioning the opening 11 of a casing 2 in the excavated site P of a ground G, and a non-circular pile B is penetrated into the excavated side P while being turned by a rotary driving source A. In this case, water is sent to the lower end of the pile B through a water supply tube D provided to the pile B for excavation. Whereupon, mud water W generated goes over the casing 2 and is trapped in the tank 1. The mud water W in the tank 1 is transported through a drain tube 5. The occurrence of pollution of the surrounding area of the excavated site P can thus be prevented by discharging the excavated soil in this manner.

Title: Glass block
Inventor: YOSHIKAWA KOICHIRO
IPC: C03C17/42
Filed: 1993-10-18
Abstract: PURPOSE:To prevent the occurrence of a crack owing to dry shrinkage by a method wherein a stress-absorbing film containing inorganic porous substance powder is formed throughout the whole periphery of the side of a glass block. CONSTITUTION:A pair of glass molded prods in the shape of a box with a bottom and a heat cover have release edges integrally welded to each other to form a glass block 20. A stress absorbing film 10 formed of inorganic porous substance powder 11, such as pearlite, and synthetic resin 12, such as acryl resin, is formed throughout the whole periphery of the side of the block 20. The average grain size of the powder 11 is preferably 10-500mum and the thickness of the absorbing film 10 is set to 100mum or less. When a compression stress is exerted on the absorbing film 10 owing to dry shrinkage of mortar, the powder 11 contained in the absorbing film 10 is properly collapsed to absorb a stress. This constitution hardly transmits a stress to the outer peripheral surface of a glass block body, relieves a tensile stress exerted on an inner surface, and prevents the occurrence of a crack.

Title: Pwm control method of current type converter
Inventor: KODAMA TAKASHI
IPC: H02M7/219
Filed: 1991-10-31
Abstract: PURPOSE:To improve the synchronous process of a power supply and control action and to suppress the generation of lower-grade higher harmonics of a supply current in the PWM control of a current-type converter according to a software system. CONSTITUTION:A synchronous detection signal is inputted to the high-speed input port of CPU and a synchronous arithmetic processing is made a non-interruption processing. First, a mean supply-voltage period for several cycles is obtained as a reference. A control period is obtained from this value for the purpose of regulating a control timing. The difference between a forecasted synchronous time to be forecasted from this reference and a detected synchronous period is obtained for each cycle. The control period is corrected on the basis of this difference. Thus, a control phase is caused to follow the fluctuation in a supply voltage. In the generation of a pulse pattern, also, it is forecasted from the forecasted synchronous time whether a power- phase voltage at the time of commutation is high or low. Then, it is predicted from this forecast whether a delay occurs or not. The ideal pulse pattern is corrected on the basis of this result so that a real current is delayed as a whole by a storage time and the generation of higher harmonics of input current waveform is suppressed.
